pplication filed Hay 22, 1914. Serial No. 840,311.

To all whom it may concern-f Be it known thatvI, JOHN W. MCCOY, acitizen of the United States, residing at Syracuse, in the countyfofMorgan and State of-Missouri, have invented new and one of the wheels ismade a part of the axle,'

while the other wheel is a part of a sleeve which telescopes upon saidaxle, thereby avoiding the fastening of both wheels to such axle t0prevent the possibility of the working loose of either wheel' therefrom.

Another object of the invention is the provision of a structure ofthischaracter wherein the axle is reinforced throughout the major portion ofits length, and the wheels and axle can be assembled in a quick andconvenient manner. A further object' of the invention is the provisionof a structure of this character wherein a washer or the like can beinterposed between" the end of the sleeve next to one of the wheels soas 'to take up wear and also allow' the wheels to be sustained at auniform distance apart, as the washer or the like can be removed for thereplacing it with a new one should the old onel become worn. A stillfurther object of the invention is the provision of a structure of thischaracter which is simple in its make-up, thereby ena/blin the quickandeasy assemblageor remova ofl suchk parts as the occasion mayrequire,l and also which is thoroughlt7 reliable and efficient in itspurpose, and inexpensive in manufacture.

With these and other objects in view, the invention consists 1n theconstruction, combination and arrangement of parts as will y behereinafter `fully described, illustrated in the accompanying drawing.and pointed out in the claims hereunto appended.`

In the drawing Figure l is a front elevation of the structureconstructed in accordance with the invention. Fig. 2 is a verticallongitudinal sectional view therethrough.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawin in detail, 5 designates the solid axle, w ich isof uniform cross sectional area throughout its length, and carriesspaced from one end a car wheel 6 which is of the ordinary wellknownconstruction, the said wheel being formed integral with the axle, whileadaptedfto telescope upon the solid axle 5 is a sleeve orv hollow axle 7which has integrally formed at one end the car wheel 8, the sleeve orhollow axle 7 being of considerably less length than the axle 5 so thatwhen tclescoped upon the latter the said axle 5 at its opposite end willproject beyond the wheel 8, and this projected end 9 of the solid axle 5is journaled as usual in journal boxes l0 of the ordinary well-knownconstruction.

Surrounding the solid axle 5 between the wheel 6 and the sleeve orhollow axle 7 at the end next to the said wheel 6, is a washer l1 whichis adapted to take up wear at this point and to sustain the wheels G and8 at a uniform distance apart, the solid axle 5 when engaged in thejournal boxes 10 holds the same and the sleeve or hollow axle Tassembled so as to prevent the separation thereof, the saidv sleeveorhollow axle 7 be` ing tapered toward the free end thereof and serves toreinforce a major portion of the solid axle vhen telescope'd thereon.The sleeve or hollow axle 7 is formed with internal annular shoulders 12forming wearing surfaces adapted to contact with the solid axle 5 at twopoints thereof, the

washer 11 being readily removed when the A samebecomes worn, so that anew washer can be replaced in its stead. i

/ From'the foregoing it is thought`that tle construction of my devicewill be clearly understood, and therefore a more extended explanationhas been omitted.`

What is claimed is A combined axle and car wheel comprising a solid axlesection integrally'formed with one of the wheels, a hollow axle sectionintegrally formed with the other wheel and reeeiving the solid ,axlesection, t-he said solid axle section being of considerably greaterlength than the hollow axle section to extend entirely through thelatter and also through and beyond the wheel integral with and the endadjacent lthereto of therewith, the salsold axle section 4loef hollowaxle section.
